According to Heffner, the affected models likely include D-Link's DIR-100, DI-524, DI-524UP, DI-604S, DI-604UP, DI-604+, TM-G5240 and possibly DIR-615. The BRL-04UR and BRL-04CW routers made by Planex Communications might also be vulnerable because they also appear to use the same firmware, he said.
The firmware updates will be listed on a security page on the D-Link website.
D-Link said that owners of affected devices can minimize any potential risk by ensuring that their router has the Wi-Fi password enabled and that remote access is disabled. In addition, users should not tale any action if they receive unsolicited e-mails that relate to security vulnerabilities.
